As'iiIlust'ra-ting on'eform of machine embodying" my--inventiorr though Without limiting' myself Yto` the precise details of construction and arrange'- 35`r ment of parts-'shownx inl the drawings and' to be' herein* described', but availing myself of' al1Y changes and modifications which* m'aybe made within the scope of the appended claims, I haveV shown-amachine whiclir willjdes'cribe by dividing 40 it into ai-number' off groups 'of'L elements.

Frame woo-lo The frame" work4 ofr the machineiconiprlses an elongatedfbedl I-3fwhich", near its-left endiasfs'hown" 45- in: Fig. '1, carries ai pair`A of upwardlyv4 projecting housings. I4.,v and--near the: centen of itslength the bed. L31 carriesar pedestal 175;.. A knee t6: isf ad!" justably mounted` on. the endet. the bed l3oppoA site to that which. carriesthe housings I4... auxiliary frame l1 projects laterally from the bed I3; as 'shownmoreclearl'y in'Fig. 3'.

which is provided, among other things, with bearings 20 and 2|, a bearing 22 being carried by one of the housings 4 and in line with the bearing 2 I, the bearings 8 and 20 being also in alinement.

Main driving connections A driving shaft 23 is mounted in the bearings 2| and 22 and carries a pinion 24 which meshes with and drives a gear 25 loosely mounted on a shaft 26 which is mounted in the bearings I8 and 20, the gear 25 carrying one member 21of a dental clutch, the other member 28 of the dental clutch being splined upon the shaft 26, the latter carrying a crank disc 29 on the crank pin of which a connecting rod 30 is mounted.

The shaft 26 has a disc 3| fast upon it, the latter carrying a pin 32.

Auxiliary driving connections The connecting rod 39 is provided with a collar 33 and the upper end 34 of the rod telescopes through a block 35 pivotally mounted on'the crank lever 36, the latter being pivoted as at 31 between the housings I4 and carrying a crank pin 38 to which a link 39 is connected, the opposite end of this link being mounted on a pin 40 carried by a slide 4| mounted free to reciprocate on the pedestal I5.

An adjusting screw 42 is mounted on a crossbar 43 and its upper end comes in contact with a plug inserted in the underside of the lever 36, the screw 42 serving as a downward movement limit for the lever36.

A pivot 44 is mounted in suitable bearings carried by the bed I3 adjacent the housings I4 and an angled lever 45 is mounted on this pivot, the horizontal portion of the lever being connected by a pair of links 46 to the horizontal portion of a lever 41, somewhat similar to the lever 45 and mounted at the upper portion of the housings I4 en a pin 48 having its bearing in the housings |4. A screw 49 is carried in cross bracket 5I) which extends between the two housings I4 serving as a downward movement limit for the horizontal portion of the lever 45. A block 5| is mounted as by trunnions between the two links 46 and above the upper surface of the lever 36 so that the upward movement of the lever 36 picks up the block 5| and raises the horizontal portions of the levers 45 and 41.

' 'I'he vertical portion of the lever 45 carries a trunnioned block through which the adjusting screw 52 passes, this screwA being provided with a nut at each side of the trunnioned block, the screw 52 being connected to a pivoted block 53 mounted on a pin-54, the latter being mounted in blocks 55 carried upon one end of a pair of rods 56 which are mounted to reciprocate in bosses 51 carried by the slide 4I.

The vertical portion of the lever 41 carries a pin 58 upon which a cranked `lever 59 is mounted, the horizontal portion of this lever being connected by links 60 to a shaft 6|. The upper portion of the cranked lever 59 carries the pivotally mounted horizontally arranged arm 62, one end of which is connected by a trunnioned block to the adjusting screw 63 which is pivoted to the horizontal portion of the lever ,59 and is provided with hand Wheels 64 and 65, by means of which the free end of the arm 62 may be raised or lowered.

The proportionate lengths of the portions of the levers 45 and 41 are such that when the lever 36 raises the links 46, the pivot pin 58 and the rods 56 move in the same direction to the same extent.

The pneumatic system As shown more clearly in Figs. 2 and 3, the pneumatic system comprises an air supply pipe 66 which leads to a distribution chamber 61 within which is a slide valve controlled by valve rod 68 to admit air under pressure to pipe 69 and hose or ilexible connection 1U, pipe 69 extending upwardly and being connected to air cylinder 1| mounted upon the upper portions of the housings I4, the hose or flexible connection 1D being connected to air cylinder 12 which is indirectly carried by the knee I6 on the bed I3. As shown by dotted lines in Fig. 1, the air cylinder 1I is provided with a piston from which a piston rod 13 (see-Fig. 4) extends upwardly and carries a block 14 on its upper end. The bifurcated lower end of member 15 is pivoted as by pin 16 to the block 14, the member 15 being fast upon the shaft 6|, the upper end of this member comprising a cylindrical portion which serves as a counterweight. A block 11 is carried by the member 15 immediately above the block 14 and these two blocks form a movement limit for the swinging action of the member 15 in one direction as will be described later. When air under pressure is admitted through the pipe 69 to the cylinder 1|, its piston is raised and through the linkage described the horizontal portion of the cranked lever 59 is raised and consequently the free end of the arm 62 is depressed to perform the functions to be later described.

Referring now more particularly to Fig. 9 the air cylinder 12 is provided with a piston 18 from which piston rod 19 extends to the interior of a housing carried by the knee I6. The piston rod 19 is connected by links 8| to lever 82 pivotally mounted in the housing 8U, to operate a toggle mechanism to be later described.

To afford a quicker release, at the proper time, of the pressure within the cylinder 12, a housing 83 is mounted on the head of this cylinder and contains a release slide valve 84 operated by valve rod 85 from connections to be later described.

A compression spring 86 is provided to normally move the piston 18 toward the head of the cylinder 12 and a similar spring, not shown, may be provided to move the piston in the air cylinder 1| downward upon the release of the pressure within that cylinder.

Hub holding devices Referring more particularly to Figs. l, 2, 3, 11 and l2, it will be noted that the rods 56 each carry a block 81 upon their ends opposite to that upon which the block 54 is mounted and by referring more particularly to Figs. 11 and 12, it will be seen that a pair of guides 88 are pivotally connected to the blocks 81 and 89 and are further connected to these blocks by adjusting screws 90v passing through arcuate slots formed in the lower portion of the blocks 81. A rod 9| is mounted in each guide 88 and these rods are connected together at their lower ends by a bar 92 and at their upper ends by a plate 93 upon which is mounted the lower hub receiving die 94, Figs. 1, 2 and 3.

Referring again more particularly to Figs. 11 and 12, it is to be noted that a dot and dash center line 95 is shown parallel with the rods 9|, and by loosening the screws 89 and 90, the guides 88 and the parts carried by them may be swung to bring the center line to the dotted line position 96 or to any other angular position required by the angular relation between the spokes of the wheel and the axis of its spindle.

Referring; more particularlyv now to Figs.. 1' 'andii 2, .itiis1seen` that the arm .62 carriesluporr its free end-- an adjustable slide 91;. adjusted ini position by screws 98- and carryingfuporr its free end a cone .Y 991 which is pivoted to. the slides 91 and angularly adjustable thereon byset screws |00. The vcone 99-moves. down. into and centers1 theupper end of a. hub which is placed upon and engaged with the. die 9.41,` the latter being'providedY with a suitable-recess or other device to engage the lower end of the hub.

The. cone 99, after it has been; adjusted. tov proper position both by'means ofthe slide 91 and the set screws |00,1 has three movements, two of. which. are vertical',4 or substantially so, while thethird is horizontal. The rst andi smaller. of thetwovertical movementsA is: that produced by the admission of air under pressure to `the cylinder 1|. .with the resulting raise ofthe horizontal portion of the cranked lever 59'r and consequent depression of the cone 99. movement isof greater magnitude than that just described. i The shaft 6| which isV located above the air cylinder 1| carriesa crank 0| fast-thereY in Fig. 5. takeV place, the rod |02. moves upward.

tothe dotted position |06` thereby moving the crank|9| to the dotted position |01 and swinging the member to the dotted. position |08, this member turning: on. the. pivot 16, thereby moving the links 60 to the dotted position |09 and depressing the horizontal portionof the cranked lever 59- tothe dotted position` |.||J,V turning this lever upon its pivot 58 and` raisingthe cone 99. to a position! considerably elevated .above the upper end of the hub to permit the hub to be either placedA upon the` machineor removed therefrom.

The third orzh'orizontal movement of the cone 991isproducediby the' raising and lowering of the lever 41 through the linksV 49' and the consequent substantiallyv horizontal movement of the. pivot 58. during the operation of thesecondary driving connections previously described;

After each spokehasbeenheaded into the hub it is necessary tol raise the hub and its spoke to disengage the spoke from the gripping dies which will be later described and this is accomplished asfoll'ows.. Referring more particularly to Figs. 1, 3, 11 and 12, the bar 92 rests upon the bar carried by a rocking. lever 2 mounted in the upper end. of a bracket 3 whichis in turn mounted upon theside of the bed |3. The rockifing; lever H2 carries crank arm ||4 which is conarranged" as they are crossing each otherrperform this raising motion. regardless of the angular adjustmentotthe guidesgfor the rods9l.

The second. vertical- Spoke headingf'tool Thespoke. heading tool comprises an, upwardly projecting Vstem*l H1 which carries, at'f itsupper end, abutton or'projection ||8, the'stem ||1"'t tinginto a holder carried by theh slide 4|. Referring more particularly to Fig. 10; thesli'd'e 4|, at theend. opposite that to which: the link 39 is connected. is formed into a. pair of'plates spaced' apart and perforated to receive/the trunnions |91;v

carried'. by theholder |20 which hasa socket |'2"| to receive; the stem |1, set screws. |22- being provided tohol'dlthe'stem in anyV adjusted'y position'.

The holder. |20. is arcuately formed at |723, toiit' withirr the'mating surface` of the end of the slide 4 thereby relieving the trunnionsl |'9 ofthe pressure during the heading operation. The lower end of the holder is connected by rod |24 to a trunnionedblock mountedbetween the down- Wardly projecting portions: oiv the slide under the" pivot for the link 39, the rod |24 being threaded and provided with adjusting nuts adjacent the block "|25 to the end that the holder |20 may be angularly adjusted and its center line moved from. the dot anddash position |26 to a. dotted position |21, this adjustment being. for the same purpose as the adjustment previously described in connection with Fig. 11.

Spoke gripping dies The upper portion of the housing 80' which is carried; by the knee I6 is provided with a pair of spoke gripping dies |28 and |29, the formerbeing carried by the cover plateY |39 while the latter is carried by the slide |3|, which has itsbearings in the upper portion of theV housing 80. The" housing 80 is vertically adjusted on theknee I5 by means of any suitable lead screw |32 and is held in adjusted position byv clampscrews |33, Figs.` 1, 2' and 3. Vertical adjustment ofthe spoke gripping dies through the mechanism just described permits these dies to be set in proper relation to the'hub carrying die 94 to accommodate the difference in distance from the end of the' hub to the center of the spoke on diierent types of hubs, and this vertical adjustment of the dies |28 and |29 is accompanied by a corresponding adjustment of the stem ||1 of the heading tool1in2itsholder |29 to the end that the button lirwilly bein alinement with the spoke receiving .gro'oves'ofthe gripping dies.V

The knee Isis longitudinallyadjustame on thebed-'i3 by means of a lead screw operated by the hand wheel |34 and is held in adjusted position by clamp bolts |35 as Well as nuts |36 on the tie rods |31 which pass through bosses |38 on the upper portion* of the knee |6and extend to the housings I4 as shown in Figs. 1, 2 and 3,

The slide |31 is provided with a vertically arranged pocket within which a pair of blocks |39 arev tted the latter being shaped to t the rounded upper end of the lever |40 which is pivoted as'at |-4| in the housing 80. The lower end of the lever |49`is attached toI the link |42 and this link is in turn attached to a link 43, the latter pair of links forming a toggle, the link |43 being pivoted as at |44 to the upper forked end of the lever 82. The link |43 is provided Withlaheel |45 which rests against a correspond-v ingpo'rtion on thelever 82, the latter also carrying a lug A|4|i through which a rod |41 passes,

the upper end of the rod being pivoted to the link |43the lowerend. of the rod beingI provided with compression. spring: |48r bearing against the un'- derside of; the, lugv |46.v When the airis released from; thev cylinder 1.2, the; spring 86.1moves` the" piston to the right in Fig. 9, carrying with it the link 8|, the lever 82 and through the contact between this lever and the heel |45 of the link 43 breaks the toggle between the links |42 and |43 and moves the upper end of the lever |40 to the left to move the gripper |29 also to the left, this being the release position of the gripper dies. When air is admitted to the cylinder 12 the piston 18 moves to the position shown in Fig. 9 but if the spoke inserted between the gripper dies |28 and |29 should happen to be too large, the toggle levers |42 and |43 will not come to a straight line position, the spring |48 being compressed thus permitting the piston 18 to move its full stroke without danger of breaking any of the linkage.

Control device Referring now more particularly to Figs. 2, 3, 4 and 6. The main control pedal |49 is mounted on cross shaft |50 which carries crank arm |5| projecting upwardly on the opposite side of the bed from that on which the pedal |49 is mounted, and the upper end of crank arm |5| is connected through rod |52 with the clutch operating rod |53. This rod carres a block |54, the latter being provided with lateral arms |55 and |56. The arm |55 embraces a rod |51 which is provided with a spring 58 and which operates clutch yoke |59 which is pivotally mounted on the bracket |60, the latter serving also as a guide for the clutch operating rod |53. The clutch yoke |59 engages the member 28 of the dental clutch and when the clutch operating rod |53 is drawn to the right in Fig. 3, the spring |58 being compressed by the movement of the arm |55 shifts the clutch 23 into engagement with its mating member 21 on the gear 25. Referring now more particularly to Fig. 6, it is to be noted that the rod |53, when the clutch is disengaged, lies within the groove engaged by the yoke |59 and as shown by the dotted line 6| there is a raised portion adjacent this groove and a second raised portion adjacent the first, making, in eifect, three different longitudinal positions for the rod |53, either at the bottom of the groove as shown in Fig. 6, or upon the step |6| or upon the outer diameter of the member 28. When the rod |53 is pulled to the left in Fig. 6, and the clutch moves into engaged position, the right hand end of thc rod 53, in Fig. 6, rests upon the large diameter of the clutch which coincides with the diameter of the disc 3|, the end of the red resting upon an inserted cam |52, .and as the clutch rotates, turns clockwise when viewed from the position of Fig. 6, the rod |53 moves in to the diameter I6 still not relieving the tension on the spring |58 and as the clutch completes one revolution, the end of the rod |53 acts upon the cam |62 definitely disengages the clutch whereupon the rod |53 moves into the shifter groove and again assumes the position shown in Fig. 6.

Still referring to Fig. 6, the arm |56 of the block |54 carries a pin which engages a rocking lever |63, which is pivoted on the bracket |60 and carries a trigger |64, the latter normally elevated at its free end by the tension spring |85. The trigger |64 passes through a slotted lever |66 carried on a rock shaft |6i mounted in suitable bearings upon the frame |1, as shown in Figs. 2, 3 and 4. A pin |63 passes through the slot in the lever |66 and is engaged by a detent |69 carried by the trigger |64.

When the clutch shifter rod y|53 is moved as previously described, to engage the clutch, the center line of the lever |63 moves to the dotted position |10, and the detent |69 coming in contact with the pin |68 of the lever |66 moves this lever to the dotted position |1|, the trigger meanwhile moves to the dotted position |12. As the clutch 28 is rotated by its engagement with the clutch 21 of the gear 25, the pin 32 carried by the disc 3| moves toward the right and then down and rst depresses the trigger |64 to disengage its detent |69 from the pin 68 and then comes in contact with the lever in the position |1| and moves it to the full line position of Fig. 6. From the above it will be seen that when the clutch is engaged, the rock shaft |61 is moved clockwise and that when the clutch has completed approximately one half of its revolution, the rock shaft 61 is moved counter-clockwise, and that upon the completion of the revolution of the clutch the parts are all restored to their full line positions of Fig. 6, the detent |69 again being ready to engage the pin 68 upon the next operation of the clutch.

The rock shaft |61 carries two crank arms one projecting above and the other below it. The crank arm |13 is connected by rod |14 to the valve rod 68 while the crank arm |15 projecting below the rock shaft |61 is connected by rod |16 with a crank |11 on a second rock shaft |18, the latter carrying a crank |19 which, at its upper end carries a pivoted connecting piece |80 through which the valve rod passes.

From the above it will be seen that when the clutch 28 is engaged, the mechanism just described wiil open the valve in the housing 61 and supply both the cylinders 1| and 12 with air under pressure from the pipe 66, and that when the clutch has made one-half'a revolution, the valve in the housing 61 will be closed to release the air from both cylinders 1| and 12, and in addition, the exhaust valve 84 in the housing 83 will be opened to permit a more rapid escape of the air from the cylinder 12 and a consequent quicker opening and release of the gripping dies |28 and |29.

To assist in maintaining the lever |66 in either its full line or its dotted line position, the tension spring |8| is provided and this spring crosses the center of the rock shaft |61 as the lever |66 is moved from one position to the other so that the spring acts to hold the lever in either its vertical or angular position, the free end of the spring being attached to a standard |82, dotted lines Fig. 2, carried by the base l1, eyebolt |83 serving as an adjustable connection at this point Operation of the machine The preliminary setting of the machine consists in placing the proper hub die 94 on its plate 93, supplying the proper headforming tool |1 and adjusting the angular relation of these parts to the, hub within which the spokes are to be placed. In addition, the cone 99 is brought to proper position with relation to the upper end of the hub and gripping dies |29 of the proper size and mounted to receive and properly hold the spokes. The elevation of the gripping dies and the headforming tool |1 is properly set, through the means previously described, to hold the spoke at proper distance from the end of the hub. The proper point for the beginning of the heading stroke is set by means of the hand wheel which operates the screw 49 and also the jack screw 42, these two adjustments determining the point of beginning of the heading stroke (the termination of the heading stroke is constant, the length of the stroke being determined by the adjustment of its beginning).

With the lever |65 moved to the left in Fig. 1, to elevate the cone 99, the operator places a hub FBO 'upon fthe machine and moves the lever to the right bringing the cone into contact with fthe zupper vend of ithe hub whereupon he rotates the hub to bring one ofthe spoke openings zintoproper position with relation rto the groove in the stationary Lspoke `gripping die. He next places a heated spoke in the groove of fthe stationary gripping die and advances it to contactwith the button I I1'8 (Fig. '7) vHeV next `depresses the 'pedal |49 and this causes the following operations to -be performed lin the following sequence.

First-Air 'is a-dmitted tothe two 'cylindersl `and"`I2 and this rmly' grips both'the `hub and the spoke.

Second-When the'clearance 'between the connecting rod 3U and its block 35 has been/taken up by the `rotation 'of the crank disc 29, the heading tool VI I 'I aswell as the hub carrying dieare ad- "holding diesA back 'tothe position theyoccupied at the beginning of .the stroke .and the crank disc 29 comes to rest, .being assisted in this operation v4by a'bra'ke r8.4 Figs. .l and 4, .which bears against the outer surface of the disc, the'latter being camshaped to relieve the 'brake pressure during part of its rotation.

By depressing 'the pedal HB, through thefmechanism ,previo,uslydescribed, the hub and 'its spoke are `raised so that the spoke clears the upper portion of the gripping dies, the spoke now being used as a handle to rotate the hub to the next spoke hole whereupon the pedal IIE is released, the next spoke inserted, the pedal I49 depressed, and the operation previously described repeated. When all the spokes at one end of the hub have been headed thereinto, the lever IOS is again operated to raise the cone 99 to permit the position of the hub with its spokes to be reversed so that the spokes adjacent the opposite end of the hub may be headed into it by a repetition of the operations just described.

When the adjustment of the machine makes it necessary to move the knee I5 or the housing 80, or both, obviously the valve rod 85 will require readjustment and to this end this rod is provided with a collar near the housing 83 and the pivoted connecting piece is provided with a screw, and by loosening this screw and setting the collar toa definite distance from the end of the stuiiing box of the housing 83, and then tightening the screw of the piece IBD, the valve rod 85 may be reset for the new position to give the proper opening and closing motions when the machine operates.

The amount by which the heading tool I I1 and its button moves further than the hub die 94 determines the amount of material gathered for the head on the spoke on the inside of the hub while the amount of movement of the hub carrying die 94 determines the amount of material contained in the collar on the spoke outside the hub, hence by adjusting the beginning of the stroke for these two operations, a proper distribution of the spoke material may be had to form the head and the collar at the hub.

Having thus fully described myinvention, I
